Abstract: Various systems and methods are presented regarding controlling respective positions of a seat back and seat base to mitigate the risk of a vehicle occupant submarining in the event of the vehicle being involved in a collision/rapid deceleration. Positioning of the seat back/seat base can be controlled in accordance with the occupant's physiology and posture, e.g., reclining. Cameras/radar sensors in the passenger compartment in conjunction with seat sensors can be generate physiology/positioning data, which can be processed, and based thereon, the seat back/base positions can be controlled by one or more motors.

Abstract: An embodiment related to a system, wherein the system comprising an alertness detector unit configured to detect an alertness signal of an occupant an alertness determination unit configured to determine an alertness of the occupant based on the alertness signal, an environment sensing unit configured to sense external data in a route, an analysis unit configured to analyze the external data to determine an external condition, a risk assessment unit configured to determine a risk level in real-time based on an analysis of the external data and the alertness of the occupant, and a control unit configured to adjust a seat if determined that the real-time risk level was above a threshold.

Abstract: A method and device for detecting and responding to impact loosening of thread joints at rock drilling, in which vibrations from a drill string (1) are sensed at the same time as a rock drilling machine (2) movable along a feed beam (6) exerts the drill string (1) to impacts without feeding the drill string (1) against a ground (3), the sensed vibrations are supplied to an analysis tool (4), the sensed vibrations are compared with known vibration patterns by the analysis tool, and a signal is sent to a control system (5) for controlling the rock drilling machine (2) for stopping an impact device of the rock drilling machine when the analysis tool detects that the sensed vibrations correspond to a known vibration pattern indicating that the thread joints have been loosened by impact.

Abstract: Method of impact loosening of thread joints at rock drilling, whereby vibrations from a drill string (1) are sensed at the same time as a rock drilling machine (2) exerts the drill string (1) to impacts without feeding the drill string (1) against a ground (3), that the sensed vibrations are supplied to an analysis tool (4), that the sensed vibrations are compared with known vibration patterns by the analysis tool and that a signal is sent to a control system (5) for controlling the rock driling machine (2) for stopping the impact device of the rock drilling machine when the analysis tool detects that the sensed vibrations correspond to the known vibration pattern which marks that the thread joints have been loosened by impact.
